WebMar 8, 2015 · You should bear in mind that the TCP/IP model only has five layers. That being said, it largely depends on if your firewall is capable of doing Deep Packet Inspection. If it is, it operates at L3/L4 and at the Application Layer. Otherwise, it only filters at the IP and Transport layers. WebIn the OSI model of computer networking, a frame is the protocol data unit at the data link layer. Frames are the result of the final layer of encapsulation before the data is transmitted over the physical layer. [1] A frame is "the unit of transmission in a link layer protocol, and consists of a link layer header followed by a packet." [2]
